Description
Port the Z garbage collector (JDK-8209683) to linux on ppc64le.
Comments
Fix Request (17u): This change adds ZGC support for PPC64. We would like to make it available with 17u. Risk is low because it only adds the new GC code which is only used when ZGC gets enabled. It applies cleanly.
